Monday's frigid temperatures forced even the hardiest crews to take a break on most outdoor construction activities in the Twin Cities.

On Monday, as temperatures dipped into the minus 20s with wind chills hovering near minus 50, outdoor work was canceled or slowed on projects such as the new Vikings stadium, the Saints ballpark, the Lafayette Bridge, and the St. Croix Crossing.

"Crews are not working outside today because of extreme cold," Jessica Wiens, Minnesota Department of Transportation spokesperson for the $626.4 million St. Croix Crossing project, said in an email.

Pile driving is expected to resume in the latter part of the week, Wiens said. The setback isn't expected to delay the overall schedule for pile driving, which continues through May, she said.

Last week, the Minnesota Department of Transportation canceled a concrete pour for the new north-bound Lafayette Bridge because of the weather. MnDOT expects the concrete pour to happen Saturday if the weather cooperates, MnDOT communications supervisor Chris Joyce said in an email Monday.
